Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TF1963U is determined by strict equivalence across the following parameters: resistance value (196 kOhms), tolerance (±1%), power rating (1W), package type (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The CRCW2512196KFKEG manufactured by Vishay Dale meets all these criteria and is classified as a direct equivalent substitute. Both parts maintain identical electrical performance specifications and are qualified for the same automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-S1TF1963U and CRCW2512196KFKEG are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on availability and supply chain requirements. The Panasonic ERJ-S1TF1963U includes anti-sulfur protection as an additional feature. The Vishay Dale CRCW2512196KFKEG offers higher current inventory availability at 2434 units. Both parts are functionally interchangeable for applications requiring 196 kOhms ±1% 1W thick film resistors in automotive environments.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512196KFKEG be used as a direct replacement for ERJ-S1TF1963U?

A: Yes. Both parts share identical electrical specifications (196 kOhms ±1%, 1W, ±100ppm/°C), the same package type (2512), and equivalent automotive qualification (AEC-Q200). Physical dimensions are within acceptable tolerances for PCB layout compatibility.

Q: What is the significance of the 2512 package designation?

A: The 2512 package (6432 Metric) is the standardized surface-mount resistor case size. Both substitute parts use this identical package, ensuring mechanical and electrical compatibility on the same PCB footprint.

Q: Are there any differences in anti-sulfur protection between these parts?

A: The ERJ-S1TF1963U includes anti-sulfur protection as a specified feature. The CRCW2512196KFKEG specification provided does not list this feature. For applications requiring anti-sulfur protection, the Panasonic part is the specified choice.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ERJ-S1TF1963U and CRCW2512196KFKEG carry AEC-Q200 automotive qualification and ROHS3 compliance, meeting automotive industry standards.

Q: What is Moisture Sensitivity Level 1 (MSL 1)?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Both parts have this rating, meaning they can be stored and handled without special moisture control procedures.
